Application filed November 28, 1910. Seria1'No. 59 4,44'4.

To all whom it may concern:

Be it known that I, WALTER BURLEY GRIF- FIN, a citizen of the UnitedStates, residingat Chicago, in the county of Cook" and State ofIllinois, have invented a certain new and useful Improvement inWindow-Adjusters, of which the following is a full, clear, concise, andexactdescription, reference being had to the accompanying drawings,forming a part of this specification.

My invention relates to the control, operation and locking of swingingwindows, and its object is to-provide an arrangement for facilitatingthe movement of the window upon the hinges upon which it is mounted, andto provide means for locking the window in any open adjusted position,or closed.-

In modern building constructionp articularly in residenc'es'whereswinging windows are used, it is desirable when a screen is used, tomount the screen on the inside of the window. It is further desirableto-permanently mount the screen inside the window, and with this inview, means has been provided for swinging the windowout-Wardly by meansof some arrangement terminating" in a handle disposed on the inside ofthe screen; i

The prior art has seen devices of this.

' screen, may when the window is locked in from the priorst-ructures in'which the point adjustment was used, that is,;where there was a limitednumber of adjusted'poi when it is considered that the window-sash issubjected to weather conditions and that it is likely to shrink, for itis obvious that such shrinkage will disarrange the point adjustmentwhichhas been --provided for.' In building equipment, it. is furtherdesirable to mount-the shade on the inside of the,-

screen, and in. the prior art devices it has been found. diflicult to dothis since'the adjustable mechanism necessitated such a considerabledistance between the window sash and the screen, the shade in thisinstance being disposed in that space. In my device however, theadjusting mechanism between the screen and the window'sash closely hugsthe sash so. that the space between the sash and the' screen need be butvery small.

Simplicity is another important object of my invention. As will bedescribed, the various. parts are of'simple construction and assembly,and the locking. is secured by a mere movement of the handle which isused to swing the sash. In the specific embodi-' ment shown, the handleis provided-with'a cam surface which is used as a jamming means when thehandle is turned, so that any further movement to swing the deviceisprevented.

As will appear,,the adjusting and locking arrangements which I providecan be moved from one side of the device to the other, so that thewindow can be made to swing the other way, andthis without anysubstantial changes in the. parts which make up; the structures. a

Other features of advantage will appear as this description proceeds. aThe various features of my invention are embodied in the device shown-inthe accompanying drawings inwhich-' Figure 1 is a horizontal, sectionalv 1ew of the wall having a window provided with my adjuster and lock;Fig. 2 is an elevat onal view thereof, parts being broken away to revealthe constructions; Fig. 3 is an isolated, elevational View of the handleand directly associated parts offlthe adjuster; Fig. 4 is an isolated,cross-sectional view of the arrangement for securing attachment betweenthe adjuster and-the window sash.

The same reference characters are applied to the .samefparts throughoutthe various figures.

/ The wall shown at l, and the window julnb which is inserted therein isindicated at 2. This window jamb is of the usual rectangular form, andis supplemented on the outside by a casing 3 and on the inside by acasing 4. The jamb is provided with the usual interior jamb surface 5,which flares outwardly as shown, and receives the Window sash 6, whichis correspondingly formed so as to insure a snug fit. This window sashof course is of the corresponding rcctangular form, and is mounted uponhinges 7, which in turn are secured to the jamb in the usual manner.

The window sash 6 is provided with the glass 8 held in place by means ofa frame 9; a stop frame 10 lines the interior of the jamb on the insideof the window, and the window sash 6 abuts against this stop frame inthe usual manner as clearly indicated in Fig. 1. This stop frame isprovided with an inside shoulder 11, against which the screen frame 12which carries the screen 13, is mounted in any suitable manner. Thespace 10 is filled with felt.

Upon the sill 1-1 of the stop frame 10, which I is of course rectangularto correspond with the other parts,there is mounted toward one sidethereof, a plate 15, preferably of metal, which is secured in place bymeans of screws 16, 16. This plate is provided with a central openingwhich is circular, and which receives the hub 17, which forms the rotaryelement of the adjusting device as will be later pointed out. The underside of the plate 15 is rabbeted as shown at'18 for the reception of aconfinin plate 19 which is secured to the under si e of the hub 17 bymeans of screws 20, 20. As is clear from Fig. 3, this plate secures thehub 17 rotatably in the plate 15.

Extending radially and obliquely from the hub 17 is an arm 21, which isscrewed in place as clearly illustrated in Fig. 1. Near the end of thisarm there is provided a slot 22, in which a link 23 is rotatably mountedby means of a cotter pin 24:. This link carries at its free end, a smalldisk 25, which slides in a pocket strip26, having the slot 27 throughwhich the link 23 proper extends, this pocket strip being secured to thesash 6 by means of screws 28, 28.

It is clear from Fig. 1 that the arm 21 is disposed between the screen13 and the sash 6, and that, when the sash is closed, it isapproximately parallel to the general lines of the sash and screenframe. The means whereby this arm is secured to the pocket strip closelyhugs the sash 6 so that the space bet-ween the screen 13 and the sash ispractically limited. The screen frame112 rests upon a strip 29, whichextends horizontally across the stop frame 10 and rests against theshoulder 11 as was described relative to the screen frame itself. Thisstrip 29 -is cut out to accommodate the plate- 15 and the hub l7,'asclearly illustrated in Fig. 2, so that an ordinary screen frame may beused without interference.

Extending from the hub 17 on the inside of the screen in a directionopposite to that of the arm 21,- is a short lug 30 to which the hub 31of a handle 32 is pivoted by means of a pivot pin 33. This hub iscircular, but is eccentric relative to the pivot pin, 33. audit is sodisposed on the pivot pin relative to the handle 32, that when thehandle 32 is in its horizontal position as shown in full lines in Figs.1 and 2, the eccentric cam thus formed will be jammed against the hub 17so that the handle itself will have a definite, positive position. Whenthe handle is in this position the eccentric hub 31 is spaced from theplate15 as shown in Figs. 2 and 3, and it is clear that there will benothing to interfere with moving the handle from left to right and backagain as indicated by the dotted lines of Fig. 1. lit is clear that suchmovement of the handle will result in the swinging of the window, andwhen the handle is in its farthermost right hand position, the window isswung open as far as it will go.

As shown particularly in Fig. 3, and as shown in dotted lines in Fig. 2,the eccentric hub 31, when the handle is changed to its verticalposition, is jammed tightly against the plate 15, so that any lateralmovement, that is, movement of the hub 17, is absolutely prevented. Thusit is seen that the hub 17 can be locked in any desired position bymerely moving the handle 32 from its horizontal position to its verticalposition, this locking action being in the way of the amming effectbetween the eccentric hub 31 and the plate 15. It is seen that when thehandle is inits raised position, it is safely disposed in the boundingplanes of the casement, and it is thus clear that whenever the window islocked, there will be no obstacle interfering with the free passage of aperson by the window.

It is important that the means of connection between the end of the arm21 and the pocket strip 26, is such that it is applied permanently atthe end of the arm for in the prior art devices, it has frequently beenfound impossible to get the proper action of the window because the endof the arm, somewhat analogous to this, has often been caught againstthe sash itself. It is clear that the pivotal connection admits of easydle being movable in one plane to actuate the swingin means and beingmovable to a plane at su stantially right angles to said first plane tolock the sash at the desired position. j

2. In a window adjuster, a casing, a window sash hinged to said' casing,means for swinging said sash, and an operating handle for said swingingmeans, said handle being pivoted andhaving an eccentric hub which actsas a cam to lock the swinging means relatively to the casing.
